[OpenLayers-Users] VectorLayer disappears at zoom 17 (and lesser).

[Andreas Hocevar]

BrainDrain and Salvaro,

I created a ticket for this:

http://trac.openlayers.org/ticket/1732

Can you please apply the patch in this ticket and see if it resolves
the issue? Or just replace lib/OpenLayers/Renderer/VML.js with the
contents of the attached zip file?

Thanks!
